[Jack-Devel] Status of cgroups support/coexistence?

On a Linux 4.2 system with realtime scheduling controlled by cgroups, what is the current recommended strategy to get jackd working as a non-root user? There was an old wiki page, https://github.com/jackaudio/jackaudio.github.com/wiki/Cgroups describing some built-in support (e.g. --with-default-cgroup configuration switch). But none of this is in the current git HEAD. (I am using jack2 1.9.11.) And a somewhat related question: Is there currently support for running jack as root and allowing client programs with multiple UIDs to connect? I tried following an old recipe using JACK_PROMISCUOUS_SERVER, but it didn't seem to make any difference; running jackd as root, only root can connect. Regards, Mark
